Specification of Letters Patent.

Patented April 3, 1906.

Application filed January 13, 1906. Serial No. 295,880.

To all whom it may concern:

Be it known that I, FRANCIS M. YENTZER, a citizen of the United States,residing in Ottawa, in the county of Lasalle and State of Illinois, haveinvented a new and useful Improvement in Hay-Carriers, of which thefollowing is a specification.

This invention relates to that class of haycarriers wherein thefork-pulley instead of iits frame is itself engaged by the grapplingcogs.

As heretofore constructed the dogs have engaged the rim of the pulley.While this construction is desirable, it is nevertheless open to someobjections, principally because the engagement with the pulley takesplace so far from its axis. The construction also adds to the height ofthe carrier, which is objectionable.

My present invention is intended to remove both of these objections andalso to give strength to the parts which they do not now possess.

The nature of my improvement is fully explained in the description givenbelow and illustrated in the accompanying drawings, in which Figure 1 isa vertical cross-section of the carrier, showing the fork pulley enteredtherein. Fig. 2 is a similar view showing the fork-pulley about to enterthe carrier. Fig. 3 is a side elevation of the fork-pulley detached.Fig. 4 is a side elevation of the pulley.

In said drawings, 10 represents a track; 11, the releasing block or stopattached to the track; 12, the car of the carrier, supported in theusual manner upon wheels (not shown) running upon the side flanges ofthe track. The rope-pulley frame is shown at 14 and is supported fromthe car by the engagement of its centrally-located outstanding circularrim with a corresponding groove in the depending portion of the car. Itsswiveling attachment permits the frame 14 to swing entirely aroundhorizontally or to make any ortion of a turn desired or necessary whenoading or unloading. The drop lock is shown at 18, and the swivelingblock or frame pivoted thereto at 23. The grapplingdogs are shown at 24.They are pivoted to the frame 14 at 25 and they are adapted both toengage and support the swiveling frame in the manner indicated in myPatent No. 777,465, of December 13, 1904. The dogs are provided withinwardly-extending tongues 31, which lie in the path of the forkpulleywhen it is raised into the frame 14, and serve as a means of shiftingthe dogs from the position of Fig. 2 to that of Fig. 1. In the latterposition the dogs are forced into engagement with the fork-pulley 40, asclearly illustrated at Fig. 1.

41 is the frame of the fork-pulley, supporting the pivot 42 of thepulley and also supporting the swivel 43, carrying the eye or hook 44,to which the load is attached. The pulley is provided on both sides ofits web with laterally-projecting flanges 45 45, the inner surfaces ofwhich are horizontal and adapted to receive and hold the grapplingdogsin engagement, as shown, while the outer surfaces of the flanges arebeveled, as clearly shown in Fig. 1. These flanges preferably extendoutward slightly beyond the rim, so that when the device is entered inthe mouth of the frame 14 of the hay-carrier they will coact with therim by their contact with the sides of the mouth of the frame 14 inguiding the pulley into place. By thus devolving this function ofsupporting the pulley upon the flanges instead of the rim I am enabledto make the rim in the form which has heretofore been customary wherethe dogs Were made to engage the frame of the pulley. I obtain also amore certain engagement by the dogs than where the engagement was withthe rim and one less liable to be broken.

I claim The hay-carrier, the fork-pulley whereof is provided withlateral flanges between its rim and hub, said flanges being adapted tobe engaged by the grappling-dogs.
